I love you girl

Story #1 Kailey came home from school today and she told me some kid named London had a crush on her bff Baley. apparently the secret was out as he told her. i asked her what crush meant she said "it means you want them to be your girlfriend"
me: girlfriend whats that?
Kailey "its when people hold hands and when they are old they kiss"
what the!!!! how does she know this after 1 week of 1st grade! not cool


story#2 she also informed me that on the bus ride home some kid a row over was sitting behind Tillman (a boy in her class) kept leaning over to her saying "I love you girl" "i love you girl" she told me she kept saying "stop saying that" and Tillman took up in her defense. what is going on! should i be worried? i don't even know how to respond to these stories!!!!
